Frequently Asked Questions
Q: Can I use only the handheld or only the lavalier, or do I have to use both? A: The SLXD4+ receiver is a single-channel unit, so only one transmitter (handheld OR bodypack) can operate at a time on this receiver. To use both microphones simultaneously, you need two receivers (or one SLXD4D+ dual-channel receiver). This combo package provides flexibility to choose which microphone to use based on the situation.
Q: How do I switch between the handheld and lavalier microphones? A: Simply turn off the transmitter you're not using and turn on the one you want to use. Both transmitters are synced to the same receiver frequency, but only one can transmit at a time. If you need both operating simultaneously, purchase a second SLXD4+ receiver or upgrade to an SLXD4D+ dual-channel receiver.
Q: What's the operating range of the system? A: Up to 330 feet (100m) line-of-sight. Actual range depends on RF environment, obstacles, and whether you use 1mW or 10mW transmitter power. For longer range, use 10mW setting and ensure clear line-of-sight between transmitters and receiver.
Q: Can I use rechargeable batteries instead of AA alkaline? A: Yes. The system works with AA alkaline, lithium, or NiMH rechargeable batteries. However, Shure's SB903 lithium-ion rechargeable battery (sold separately) is specifically designed for SLXD+ transmitters and provides accurate battery metering, longer runtime, and faster charging compared to standard AA rechargeables.
Q: How many SLXD systems can operate simultaneously? A: Depending on your frequency band, you can run 11-14 systems in a 6-8 MHz TV band. For larger channel counts, use Wireless Workbench® software to coordinate frequencies across multiple systems and avoid interference.
Q: Is this system compatible with my country's wireless regulations? A: The SLXD124+/85 is available in multiple frequency bands for different regions (G50, H55, J53, L50, M-band, etc.). Verify that you purchase the correct band for your country. The "M" in SLXD124+/85-M indicates the frequency band—confirm this matches your local regulations.
Q: Can I replace the SM58® with a different microphone capsule? A: Yes. The SLXD2+ handheld transmitter accepts interchangeable Shure capsules including Beta 58A, Beta 87A, Beta 87C, SM86, Beta 57A, and others. Simply unscrew the SM58® capsule and attach your preferred capsule.
Q: Can I use a different lavalier microphone with the bodypack? A: Yes, but the microphone must have a TA4F connector (4-pin mini XLR) compatible with the SLXD1+ bodypack. Shure offers WL93, WL183, WL184, and other professional lavaliers. Third-party lavalieres with TA4F connectors may also work but performance will vary.
Q: Does the system require licensing or frequency coordination? A: In most countries, UHF wireless microphones operate in licensed spectrum or shared bands. Check your local regulations. You may need a frequency license depending on your region and frequency band. Wireless Workbench® can help with frequency coordination.
Q: What's the difference between SLXD and QLXD or ULXD systems? A: SLXD+ is Shure's mid-tier digital wireless platform with professional features at accessible pricing. QLXD offers similar quality with different feature set (no ShowLink® Ease). ULXD is Shure's flagship touring system with higher channel density, Dante networking, and advanced features. SLXD+ is ideal for permanent installations and portable applications where ULXD features aren't required.
